This entity is a candidate. One public signal put it on the graph (named as the family office administering 2 private foundation(s) with $711,350,300 in assets (IRS in-care-of); one family or several is unread); it is not counted as a confirmed family office and nothing below should be read as saying it is one.

Each reading is 0 to 100 from the listed components in the evidence section; hover a tile for what it measures. No evidence yet of: direct investing, external managers, private markets, sponsor-friendly, real estate, co-investment.
